There are many ways to make money online or not online. But your choice must be guided by what kind of work you know to do or what talents you have. For example, online, webmasters can earn a lot of money. It depends also on what country you live in. If you think about earning money online, the best is to select several types, because in only one way, it will not bring you too much money. Maybe it is a good time to discover yourself to see what your talents are.
In my case, I love writing articles. The advantage of writing articles on certain sites is that you can earn in multiple ways: upfront payment, bonuses, and then lifetime earnings from your articles views, contests and marketplace. The conditions are quality and no plagiarism, in most sites with article writing.
There are also sites that pay for digital photos or videos if you have such talents. Also you could resell something online. It is more complicated, but a good choice to make money.
You have just to discover your talents and you will see there is always a way. Good luck!
